- the side marker lamp 200 provided at the vehicular lamp 10 may include a light source module which includes a light source 271 and a substrate 270 , an optic lens 280 , a guide portion 210 , and a socket portion 290 .
- the light source 271 emits light based on an electrical signal.
- the light source 271 is not limited thereto and may be a variety of light sources such as a laser diode (LD), a bulb-type lamp, and the like.
- a plurality of such light sources 271 may be provided to satisfy a necessary light amount, and an arrangement of the plurality of light sources 271 may be diversely varied.
- Such light sources 271 may be arranged to be mounted on the substrate 270 .
- the light source 271 may be arranged in a direction to which light is to be emitted, that is, from the front and rear of a vehicle toward the sides.
- the substrate 270 is electrically connected to the light source 271 and may perform a function of supporting the light source 271 . Also, the substrate 270 is formed of a plurality of circuits formed on a surface of a base material and may receive currents supplied from the outside and a signal related to whether a light source is to be turned on from a controller.
- the substrate 270 may turn on or off the light source by inputting a turn-on or turn-off signal to the light source 271 through the plurality of circuits formed on the surface thereof.
- the substrate 270 may have a panel shape with the light source 271 disposed on one surface thereof and may be slidably attached to or detached from the guide portion 210 .

- a terminal 272 for providing electrical conduction by having a connection with the socket portion 290 may be formed on a front end of the substrate 270 .
- the optic lens 280 performs a function of diffusing light emitted from the light source 271 . As the optic lens 280 diffuses light, the number of light sources 271 may be reduced and light emission efficiency may be improved.
- a knurling pattern may be formed on a surface of the optic lens 280 to scatter light. The pattern may be formed to be in a dot or line shape and may be formed in a variety of figures.
- the optic lens 280 may have a panel shape, be disposed adjacent to the substrate 270 , and be slidably attached to or detached from the guide portion 210 .
